A synthesis of 6-azabicyclo[3.2.1]octanes. The role of N-substitution

A new synthesis method is described for the aziridine required for the aziridine-[pi]-nucleophile cyclization for preparing 6-azabicyclo[3.2.1]octanes. The studies have shown that N-diphenylphospinyl and N-H aziridines have not led to the desired bicyclic ring systems, whereas a nosyl group on the aziridine nitrogen has led to the bicyclic ring system.
